Auranticarpa rhombifolia is a rainforest tree of eastern Australia. It is commonly called Diamond Leaf Pittosporum, Holly-leaved Pittosporum, Hollywood, Diamond Leaf Laurel or White Myrtle. The former botanical name is Pittosporum rhombifolium. The tree may grow up to 25 metres in height and a trunk diameter of 45 cm. It is widely planted in many parts of Australia as an ornamental. The white flowers and orange fruit make it an appealing street or garden tree.
The tree flowers in late spring and early summer. The flowers are arranged in an inflorescence known as corymb, a modified raceme in which the lower pedicles are longer than the upper pedicles so that the total inflorescence appears flat-topped.
Each flower possesses 5 pale green sepals, 1–2 mm long; 5 white petals, 5–6 mm long; 5 stamens; an ovary with 2 carpels.
The ovary has 2 carpels. Each carpel contains a few large ovules.
Mature fruit is an orange pear shaped capsule, 5 – 10 mm long with two or three oval black seeds.
The bark is grey, irregular, not smooth and almost corky.
Leaves are clustered in pseudo-whorls. Mostly rhomboid or diamond-shaped. Margins irregularly and coarsely toothed in upper half.
I would like to thank Ms Seanna McCune, Curator of National Herbarium of New South Wales for her kind support and guidance.
